In the summer of 2016, the town of Pomfret, Connecticut, applied a rejuvenator product on some streets and controversy ensued. Sealants and rejuvenators are different paving products, but much of the controversy centered on a class of ingredient some sealcoats have in common with rejuvenators, namely refined coal tar derivatives.
PCTC weighed in on the controversy in Pomfret in an Op Ed in The Norwich Bulletin . Read it here.
Pomfret retained an engineering consultant to evaluate and report on the situation; the report is available here. In its discussion of sealcoat, the engineering firm followed the lead of the Connecticut Department of Health, which relied on information disseminated by the US Geological Survey (USGS) to evaluate health risks that could be posed by refined coal tar derivatives. The USGS has demonstrated no expertise in this area – that agency relied on a 3-decade old US Environmental Protection (EPA) evaluation that was known to everyone who is paying attention to be at least 2-decades out of date. Just this past week, however, EPA revised that assessment, which pulled the rug out from under the USGS (& Baylor) “risk assessment.”
